Semax: Nootropic & Neuroprotective Peptide

Research on the ACTH-derived peptide for cognitive enhancement and brain health

Source: https://indexalabs.com/blog/semax-nootropic-neuroprotective-peptide Abstract: Semax is a synthetic ACTH analog developed in Russia with potent nootropic and neuroprotective properties. This guide explores its mechanisms, research evidence, and applications in cognitive enhancement.

1. Overview

Semax (Met-Glu-His-Phe-Pro-Gly-Pro) is a heptapeptide based on the ACTH(4-10) fragment with a C-terminal tripeptide extension (Pro-Gly-Pro) that enhances stability and neurotropic activity. It is approved in Russia for stroke recovery and cognitive enhancement.

2. Mechanisms of Action

2.1 BDNF & NGF Expression Semax significantly increases brain-derived neurotrophic factor and nerve growth factor expression.

2.2 Melanocortin System Activates melanocortin receptors involved in learning, memory, and neuroprotection.

2.3 Dopamine Modulation Enhances dopaminergic transmission, improving focus and motivation.

2.4 Neuroprotection Provides protection against oxidative stress, excitotoxicity, and ischemic damage.

3. Research Evidence

3.1 Stroke Recovery Clinical studies in Russia demonstrated improved outcomes in ischemic stroke patients.

3.2 Cognitive Enhancement Research shows improvements in memory, attention, and learning in various models.

3.3 ADHD Research Studies on attention and impulse control in ADHD models.

3.4 Neurodegenerative Models Research in Alzheimer’s and Parkinson’s disease models.

4. Research Protocols

4.1 Available Sizes Semax is available in 10mg vials.

4.2 Intranasal Administration Most research uses intranasal delivery for direct CNS effects.

4.3 No Hormonal Effects Unlike full-length ACTH, Semax does not stimulate adrenal cortisol production.
